One technique you can use is a "scope guard"; an object which goes out of scope when a scope is exited. When it goes out of scope, its reference count drops to zero and its DESTROY method is called:

# use 5.014; use warnings; my $CleanExit = 0; { package My::ScopeGuard; sub DESTROY { return if $CleanExit; say 'cleaning up'; } } # this is the object that will go out of scope my $guard = bless {}, 'My::ScopeGuard'; say 'doing something'; die "Oh Noez"; # or if everything works fine: $CleanExit = 1;

Now we can test it likes this:

$ perl -wE 'do ""; say "Back in master"' doing something cleaning up Back in master

You can see that the cleanup happens before the the rest of the calling code.
